I can't identify which rpm this is, if it is one. I can't find it on copper coins. It almost looks like a 3 or maybe a 5. It doesn't look like D over D to me. Thanks for your help


Oh is this D over D over D? FS-1954D-501?
Mine seems to curve more inside the primary hole almost like a 3 I think mines different? Mines goes back down while FS-1954D-501 just goes horizontal

mine is on the left
